Scalebound: As a Platinum fan, I think this will tank unless they get a better showing this year. Each time I've seen the game it looked clunky and unfinished, with the boss fight showing last time played by someone who wasn't good at video games making it look even worse, and the protagonist + music come off pretty try-hard. I should want this game though, it looks like action/RPG Dragonheart. Nier on the other hand seems lower budget and in a better state, so I guess they have that.
Agents of Mayhem: Yeah, the marketing has been weak, and they haven't kept any momentum or showed any cool new features that keep it in the conversation. Big games live/die on hype, and unless it is a huge critical surprise, I can't see it doing well.
Sea of Thieves: I think it was a mistake to go the streamer route for marketing with this game, enough that it kept me from paying attention to it vs. a real walkthrough of what you do in it. I just don't know anyone that talks about this game.
Gravity Rush 2: Unless they were really conservative with budget, I can't see this doing well.
Vampyr: Not many people are talking about it, all of the gameplay segments look like poor man's Dark Souls combat, and the art direction I don't think even props it up like Remember. Though given Remember Me, I'm not surprised the gameplay looks like a weaker version of a game I've already played before.
State of Decay 2: Were enough people into the 1st game to want to jump on board with a sequel? I don't think so at least.
Resident Evil 7: Unless they were also conservative with budget, I just don't think this title will sell AAA numbers. The games it takes influence by were indies sold for a portion of the cost, and not that far behind in terms of production values.
For Honor: Unless this title is a surprise critically, I don't think it will sell to that big of an audience to afford the money Ubisoft puts into production values. The single-player campaign showings I don't think have been strong, as it doesn't help that regular grunts go down in one hit, rather than utilizing any aspect of the unique controlling combat system.
Overkill's The Walking Dead: Remember this game...I didn't either until I looked up upcoming 2017 games. After Overkill's not great handling of Payday 2, I question if they can create a hit out of this, especially with multiple other Walking Dead games being critical and commercial flops.
Ghost Recon Wildlands: Another Ubisoft game that looks really expensive, doesn't have much of a personality, the alpha/beta whatever thing I tried was a buggy everything turned pink (this actually happened) mess with convoluted UI, the narrative feels barely there, and it doesn't evoke much of the Tom Clancy tactical shooter past.
Halo Wars 2: Halo as an IP has diminished both in relevance, sales, and critical reception...so how is a sequel to an RTS that moved a fraction of the shooter numbers going to be a success? All my memory of the first was it was a competent at best RTS, hamstrung by gamepad controls, and the last game Ensemble Studios released before dying (thanks Microsoft). Not to mention RTS as a genre is less relevant (sucks, but true).
Day's Gone: If it comes out in 2017, I'm calling flop. It's the most generic by the numbers big AAA exclusive I've seen Sony show this gen. There is no compelling hook or unique feature, no amazing story or characters on show, and just another zombie thing.
